Genes affected

ADGRV1 (HGNC:17416): (adhesion G protein-coupled receptor V1) This gene encodes a member of the G-protein coupled receptor superfamily. The encoded protein contains a 7-transmembrane receptor domain, binds calcium and is expressed in the central nervous system. Mutations in this gene are associated with Usher syndrome 2 and familial febrile seizures. Several alternatively spliced transcripts have been described. [provided by RefSeq, Jul 2008]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Gln1315Lys variant in ADGRV1 has not been previously reported in individua ls with hearing loss or Usher syndrome, but was identified in 1/15284 African ch romosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitu te.org; dbSNP rs764685377). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Comp utational prediction tools and conservation analyses do not provide strong suppo rt for or against an impact to the protein. In summary, the clinical significanc e of the p.Gln1315Lys variant is uncertain. ACMG/AMP Criteria applied: PM2.
